Hi,
I know I have seen it somewhere, but cant find it now! What is the actual rear axle ratio on a row-crop 01 series tractor after it passes through and is altered by the set of bull gears to the rear tires?
What is the reduction (or the number of teeth on each gear in the pair) value of the gearset?
Thank You!

Thank You Bob!
Sooo... the ring and pinion in this tractor are 43 and 6 teeth, 43 divided by 6 = 7.17 so the ratio coming out of the differential and going down the axle shaft into the 15 toothed bull gear is 7.1:1. The bottom 32 toothed gear divided by the upper 15 toothed gear is 2.133:1.

7.17 MULTIPLIED by 2.133 = 15.29361, so the final ratio at the wheel is 15.29:1?

THAT seems awfully low!

maybe it should be 7.17 + 2.13? That would equal 9.3, and a final ratio of 9.3:1 sounds far more reasonable than 15.29:1!

not add, multiply.
